Application filed February 14, 1Q. Serial No. 148,521.

To all 1127mm it may concern. H Be it known that I, Boom: G.C.-xsnan1ar:,

citizen of the "United States, residing at lVashingt-on, in the Districtoi" Columbia,

have invented certain new' and useful Improvements in Removable Fiyelcts for Passmg Electric Conductors Through Rugs, of which the following is a specification.

Ininstalling telephones,"call-bells, etc, on desks it is now often necessary to run the wires thereto down from-the ceiling, in order to avoid cutting or punching holes in the valuable carpets or rugszupon which the desks rest, and this invention has for its object to provide means whereby the wires may be led through the rugs or carpets without removing any part thereof, or cutting them or the fibers thereof, and for this purpose it consists of a perforated base disk having a threaded conoidal point thereon, part of which is removable, adapted to be screwed through the mg, pressing,' the fiber thereof apart, and'a perforated top disk adapted to be locked to thebottoni disk, the

wires to tlm'two disks, and itfurther consists in the construction, arrangement and combination of the several parts of which it is composed, as will be hereinafter more fullydescribed and claimed.

Referring tothe accompanying drawings by like] marks of refercncef Figure 1 is a perspective view showing the manner of using my invention,

showing a modified form of mymvention with the removable point in-full lines.

The .base A comprises a dish a, and stem a, both disk and atom being centrally perforated as at a. and the atom having a female thread a" around its central perform" tion to receive a corresponding male 6 upon thereduced. stud b, pro'ecting from the lower end of the removal 0 point B, which exterior of the point ll being threaded as at I", tbe thrends thereon being continued, as at it, upon the exterior of the stem 0- of tho baseA; r

In use the stud upon the lower end of the point B is screwed into theistenrof the base and'the point is then screwed into the rug from the lower side thereof at the point at which it is desired to pass the wires there- .through', being. turned be the base disk, the edge of which may be milled as at 0",while .nS'additionnl means of grasping the base diskI prefer to form perforations :1 therein, which may be engaged bya suitable bi intheart."- V i The point ll having been thus worked through the rug, the screwing motion is continued until. the base disk, is by means of tluruds If and oflln'onghtup tightly against the lower surface of the rug, when the up per disk I) is phu'ed over the point B. The upper disk eoniprises the flange portion (1 fureated.wreneh of a charm-tor well known:

and tin-stein 2]. both perforated as at viii female threads 1/ surroumling the apertureainl ofnfsuitable pitch and shape to correspond with the threads (1. upon the stem of the base disk. The upper disk being; properly placed upon the point it is rotated.

ther conhv means of'the milled edge 1 and its female tlneada engaging the male threails'n upon the base 'disloavhereby the two disks are caused to approach each other ti htly clam )lll a position shown in full'lines in Fig, 2, after which wires may :be threaded as desired, through the opening formed by the registering, perforations a. and d in the lower and upper base respectively.

It will be seen that as the aperture through the ra is formed by the rigid atoms a and d the wires may be disconmeted and drawn through as often as it may be desired to remove the rug for the pur ones of cleaning, this being impractica-b e when the wires are carried through the rug without an eyelet, unleiri a lar 0 hole is out therein, as the elasticity of tlie fiber would tend to close up the out and bind on the when which would cause them to he caught and broken, as the wires were drawn through.- It will also be seen that the rug lmtween-them." T 0 point B IS tlicn removed by unscrewing when it is desired to discontinue the passage of the wires through the rug the two 'disks may be screwed apart and the lower term], for instance, stamped out of sheet steel, or made-of brass, and in some cases it may be desirable to have the base of the point B of such diameter as to permit the threads d of the upper disk to enga ethe threads I) thereon, as by so doing the evice may be used with rugs the pile of which is so heavy as not to permit the upper disk being directly engaged on the t reads a of the lower disk. After engaging the threads of the point B no difiiculty will be experienced in compressing the pilesuflicientl to enga e the upper disk with the three s upon t e lower one. construction is adopted the threads 6 and b on the point should have the same pitch distance in order that in' unscrewing the point from the lower disk, it also unscrews from" the upper disk without binding.

' Having thus described my invention what I claim and desire to secure by Letters Patent is: i

1. In a device for assing conductors through rugs, the com ination of a base havin 'an externally threaded rforated stem t ereon, of an upper disk avin an internally threaded perforated stem t ereon, adapted to engage the threads .on the base stem and a point removable from the stem on the base and adapted to be rotated by the base, substantially as described.

2. In a device .of the character described, the combination of a base, having a threaded perforated stem, an externally threaded point removable from the stem, and'an.up-

When this 'the combination of a base, having a threaded perforated stein, an externally threaded I point removable from the stem, and an uper disk having an internally threaded perorated stem thereon adapted-to engage the threads on the base stem and on the point substantially as described.

4. In .a device of the character described, the combination of a base comprising a perforated disk and a perforated stem, the stem being internally and externally threaded, an externally threaded point adapted to engage the internal threads in the stem of the base, and an upper disk, comprising a perforated fiangeportion and a perforated stein, internally threaded to engage the external threads on the stem of the base, substantially as described.

5. In a device of the character described,

the combination of a base comprisinga per:

forated disk. and a perforated stem, the stem being internally and externally'threaded, an externally threaded point adapted to engage the internal threads in the stem of the base, and an upper disk, comprisin a perforated flange portion and a perfora d stem, internally threaded to en ge the -external threads on the stem of t e base and on the point, substantially as described.

6. In a device for passing conductors through rugs, the combination of a base,

having a hollow perforated 'stem' thereon,

an upper disk ada ted to be secured to the stem and a point orming when in place) rigid continuation of the stern and remov able therefrom, substantially as" describedl In testimony whereof I afiix my signature.
